Well, sort of.

Yes, please look at it again.  There is a ';' here.

I'm not talking about the prototype, but about the actual use of the
function, i.e. the FUNCTION-BODY argument of AC_TRY_COMPILE.  You are
right in one way, that a final ';' is indeed added by autoconf after
pasting that argument literally into the main() function.  But we should
use it consistently, and the current style of KDE_CHECK_FUNC_EXT usage is
to have that argument by a complete statement.
